At the same time there are important disadvantages to using the power-of-two (P2) FFT, in particular limits on the number of reachable transform sizes that make it difficult to match data set sizes ...

The fast Fourier Transform (FFT), added to an oscilloscope or digitizer, permits measuring the frequency domain spectrum of the acquired signals. This provides a different and usually helpful ...

create multiple files that each contain one graph. You can send the graphics output to external files either at the time you run the program that creates the graphs ...

Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...
